Biogas developer, GreenWhey Energy has secured $28.5m of finance to construct and operate a wastewater anaerobic digestion facility which will treat food waste carried in wastewater local food companies in Wisconsin, US.

The project is expected to be one of the largest facilities of its kind in the US processing some 500,000 gallons (1.9 million litres) of wastewater from the local dairy industry.

According to Greenwhey the wastewater is diluted with whey and milk, and is packed full of fats and proteins which carry a lot of innate energy.

The electricity produced by the project will be sold to Xcel Energy (NYSE: XEL) and according to the developer will be enough to power 3,000 average Wisconsin households.

The heat produced will be sold back to local factories reducing the amount of natural gas needed to run industrial processes, while bi-product from the digester process will be turned into clean and organic fertiliser to offer area farmers a nutrient rich soil supplement.

The project is expected to be completed in summer 2013.
